It is illegal to dump materials in the streets and or curb and gutter.  Alternatives need to be addressed.  Good housekeeping must be maintained per the City of Pueblo’s MS4 (Multiple Storm Sewer Systems) Permit with the State of Colorado.

 As it states in the City of Pueblo Code of Ordinances……

(3.5) Illegal discharge means any direct or indirect spill or discharge of any substance, other than stormwater drainage runoff and naturally occurring groundwater, to the City's Storm Drainage System; 

(6.5) Pollutant as used in this Chapter means any contaminant of water discharged into  stormwater facilities except those which are naturally occurring in stormwater runoff and area groundwater. Pollutants include, but are not limited to, the following: paints, varnishes and solvents, oil, antifreeze, transmission fluid, debris, automotive fluids; off-site tracking of pollutants.  

(a) It shall be unlawful and a municipal offense for any person to make, conduct, engage in or knowingly permit or suffer to exist any illegal discharge to the City's Storm Drainage System.

Where no specific penalty is provided, the violation of any provision of this Code adopted herein shall be punished by a fine not exceeding one thousand dollars ($1,000.00) or imprisonment for a term not exceeding one year or by both such fine and imprisonment, the amount of such fine or term of such imprisonment to rest within the discretion of the Municipal Judge.  (Ord. 7937, 12-8-08)

The Basics of Illicit Discharges

• Illicit discharges are defined as a storm drain that has measurable flow during dry weather containing pollutants and or pathogens. A storm drain with measurable flow but containing no pollutants is simply considered a discharge.
• The mode of entry can either be direct or indirect. Direct means that the discharge is directly connected to the storm drain pipe.
• Indirect means that flows generated outside the storm drain system enters through storm drain inlets. 
• The frequency of dry weather discharges in storm drains is important, and can be classified as continuous, intermittent or transitory.
• Continuous discharges occur most or all of the time, are usually easier to detect, and typically produce the greatest pollutant load.
• Intermittent discharges occur over a shorter period of time(e.g., a few hours per day or a few days per year).
• Because they are infrequent, intermittent discharges are hard to detect, but can still represent a serious water quality problem, depending on their flow type.
